Solution for:HTC Desire back button (and others) not working good after a while

Dear all,
I'd like to share a solution with the global HTC Desire community to the "buttons not working properly" issue.
My problem was that after a few months of use, some buttons of my HTC Desire began to not be as responsive as before.
It started by the "back button" and then the "home button" ; I had to push harder on it to get it work.
I saw several topics on this subject and no one proposed a solution that was really working.
Some people were saying that it was a software issue but as I had changed everything on my Desire since the first day I got this issue, I was sure it was hardware related.
I was about to follow the disassembly tutorial on youtube to have a look at the buttons more accurately but my father proposed to use a "moisture remover" before.
The product is this one but I'm sure some equivalent can be found:
MicroCare MCC-DC1 - VeriClean™ Flux Remover - 10 oz Aerosol Can
Basically, from what I understood, it helps to dry the parts where you use it (might help also from swimming pool issue...).
We turned off the phone, and used it directly on the buttons, trying to get the product inside (the buttons are quite loose so it was definitely feasible).
I turned on the phone 1min later and I'm still very impressed of the result.
Every button are now working properly (no need to press harder) and they react like the first day I got my phone. This is is very impressing and for all who might have the same issue than me I'd like to see if it works for everyone. It seems that my phone got wet some day (which doesn't surprise me at all) and the wetness never left, messing with the buttons.
Let us know if I'm right !
Cheers !

So, is it still working?

Thanks for the tip. Had the same problem with my year old Desire. I just tried this with some PCB & Flux cleaner from Maplin (£3.99) and so far it seems to working much better.
Will see how long it lasts.

hi all
same problem here
do you think that crc 2-26 will do the trick? http://www.google.it/search?q=crc+2...=mode_link&ct=mode&cd=1&sqi=2&ved=0CC4Q_AUoAA is it similar to what you used? i meanm is it a simple electronic pray (yet "liquid") contact cleaner?
i'm a little afraid of using that on the phone... i tried compressed air but didn't work
thanks
luca

Thanks, i got this issue with the volumebuttons

Hope this help to my phone's volumeUp button.

Me too struggle to get it to go into recovery.

I'm based in Sydney, Australia
Following your advice I found a similar product in a Auto shop
I bought a can of Contacts Cleaner, non conductive, plastic safe and leaving no residue
AND IT WORKED PERFECTLY
THANK YOU SO MUCH

boot into fastboot (back & power)
Code:
fastboot oem gencheckpt
or from system
Code:
adb reboot recovery

My back button is starting to die too!
Will definitely look into the solutions posted in this thread!

I had this trouble and found an app called 'Button Savior' which displays an icon on the screen that when tapped displays a 'strip' of buttons onscreen (Home, Menu, Back etc)
It requires root for full functionality and as I am rooted I don't know what functionality it would have for un-rooted phones.

say it also works for the volume button? if I do not crush very strong does not work ... it is for what?

It has Home, Menu, Power, Back, Phone, Search and Camera buttons.
There is also an app callled 'Volume Widget' which allows you to put a widget on a screen to turn up or down the volume for Call/Music/Ringer etc.

tried it and it stained my screen....streaks shooting up when white

Man, your father is a genius. It worked perfect for me, got myself a KONTAKT LR spray (easier to find in switerland) which does the job at 100%, my back button is working perfect now, the volume button is also like new. Thank you guys.

Yes !

Yes ! It really works!
I have a HTC Desire brown and my Home, Menu and volume down buttons were barely working.
I used MicroCare MCC-DC1 - VeriClean™ Flux Remover - 10 oz Aerosol Can
because the suggested product above is not available here in Belgium.
I removed the back panel and the battery. Then carefully sprayed some flux remover on the malfunctioning buttons, waited a minute and done!
Thanks so much to you and your dad for sharing this solution !
I can really recommend it to everyone with this problem.

[Q] Keyboard Shadow/Outline on Homescreen

Hello. Just picked up a used GNex off Craigslist. My old Nexus broke and after 2 weeks wn old Dith aroid 2 Global that someone let me use, I had to get a GNex back. It came rooted with CM 10.1. However, once I got home and started messing around with it (flashed AOKP and installed TWRP) I noticed that there was a shadow/outline (not really sure how to describe it) of the keyboard on the screen at all times. It's not the worst thing in the world, but it is pretty annoying (especially on pages with white backgrounds.) I'm pretty sure I did nothing to cause this but does anyone have any idea what is going on/how to fix this?
Sidenote: I just realized that the keyboard outline is not "on the picture" if you will. I took a screenshot, looked at it on my computer and the keyboard outline was not on the picture. Not sure what this means/if it helps.
I've tried to take a picture of my phone but they keyboard outline is too faint to pick up.
Any help is greatly appreciated. Thanks!

Your new galaxy nexus is suffering from severe burn in. Remember on amoled screens, stuff displaying on the screen sort of burns the picture into the screen. Download screen diagnostic from the play store. Take a snapshot of the screen with the keyboard open. Then load the snap shot in screen diagnostic. Leave it there for a bit and it should fix the burn in.

for how long did you leave the negative image on? i have a similar problem on my s4 and i made a screenshot of my whatsapp chat box with the keyboard on (like the burnt image), turned it into a negative using the app and left it there for about 15 mins and the burn is still there like before.

I think I left mine on overnight. I didn't remove it completely, but it improved it

Touchscreen problem

I recently cracked the touchscreen of my device.The glass was cracked but the touch was working fine.But i decided to get my screen replaced anyway and now, the new screen is being kinda wonky.It sometimes doesnt register my touch.Its alot jumpy now.To understand this assume that the you are trying to draw a spiral or a straight line on the snote app through your finger.The line /spiral that you will get in the end will not be continuous and will essentially be broken at different places even if your finger was constantly touching the screen.Also,when i try to drag the icons on my homescreen, the screen just drops them at the random places.
Long story short tye new screen isnt working well with continuous input.I cant even use the swype capability of my keyboard.Any suggestions?I have included a screenshot .

Automatic launch apps

Hello all,
Just got my Galaxy Tab and it's great but i got 2 minor issues:
1. It lags, but I am sure an update will fix this... I hope xD
2. Sometimes in home screen it automatically launches an app without me touching the screen. Not even a finger is near the screen. Do you guys have it too?
In browsers, apps it does not automatic click something.

What app?
My guess would be its bloody My Magazine app. Double click the home button then press the menu button then setting and uncheck the box that says open with home button.
Hopefully I guessed right lol

Install this app you might have a faulty screen, it has been found on a few Note 10.1 2014. There is a thread for it somewhere on here.

Does the ghost touch always touch the same spot? This happened to me for a while, right after unlocking the screen sometimes I would get a ghost touch in the same spot. Apart from that it did not affect anything else, the ghost touch only occurred from time to time after unlocking. After a while it went away don't know what changed exactly. Maybe try restarting the tablet see if that helps. I haven't had a ghost touch in ages.

I got the feeling the ghost spot is at random because always other programs are launched from homescreen.
They are charging way to much for a laggy, faulty device.
I reduced the lag though, so now rest the screen xD

Get a replacement tablet if you can.

The s pen features stopped working

I made this account to adrress the issue here, as ive not seen someone realy give an answer before apart from 'restart your device' or 'turn air command on'
The story s short: one day it worked, the other day i updated the tab to 4.2 and then it stopped working... i went back to 4.1 and it still didnt work, so now im stuck without being able to open the menu, nor can i use the button related features.
Ive tested my s pen on other note, and it works perfectly too, so im sure it has to do with my device.
Any help, ideas or well... anything???
Thanks in advance

Maybe i somehiw turned it off, then it dssapeared then when i went back to 4.1 i lost the option to actually turn it on??????

There was is Air Command in Note 8.0. Air command was introduced with Note 3.0
however, if you mean the "quick command" then you press the button on pen and drag from bottom of screen towards top.
and that should bring out the panel for you.

S pen not working
I have an Note 8 N5120. I have also lost access to my pen. The pen itself works fine on my Note 2. It is possible that it was related to the latest update to version 4.2.2. I do not have any idea how to get access back. I am probably going to do a factory reset but I didn't really want to lose my level in Candy Crush . Rooting is another possibility and of course it could be the proximity sensor hardware in the device. If anyone else has run into this and then fixed it please let us know.
